1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Bacteremia, a leading cause of death, generally arises after bacteria establish infection in a particular tissue and transit to secondary sites. Studying dissemination from primary sites by solely measuring bacterial burdens does not capture the movement of individual clones. By barcoding Klebsiella pneumoniae, a leading cause of bacteremia, we track pathogen dissemination following pneumonia. Variability in organ bacterial burdens is attributable to two distinct dissemination patterns distinguished by the degree of similarity between the lung and systemic sites. In metastatic dissemination, lung bacterial clones undergo heterogeneous expansion and the dominant clones spread to secondary organs, leading to greater similarity between sites. In direct dissemination, bacterial clones exit the lungs without clonal expansion, leading to lower burdens in systemic sites and more dissimilarity from the lung. We uncover bacterial and host factors that influence the dynamics of clonal sharing and expansion. Here, our data reveal unexpected heterogeneity in Klebsiella bacteremia dynamics and define a framework for understanding within-host bacterial dissemination.
